1. Introduction
The TRP-C24H is an Isolated open collector digital outputs Modbus TCP Module, It provides 16 channels output
open collector signal (100mA) to driven your devices on network, It supports 3 communication Protocols, TRP-ASCII,
Modbus RTU / ASCII, It can be easy and convenient to use application supports Modbus.
Software engineers can use the TRP-ASCII or Modbus RTU/ASCII command set quickly and easily integrated into
the self-development program, such as Microsoft VB, VC...
The TRP-C24H built-in independent IP, WEB-browsing more convenient to rewrite the configuration and collect
information through computers, tablet computers, smart phones, will be available!
The TRP-C24H built-in watchdog Hardware ensure the normal operation of the module, and a built-in voltage
monitoring to ensure that the boot, excellent and advanced hardware for harsh environment.
The TRP-C24H can TRP-C26H, 16 remote control directly, do not need to run the software and equipment.
When TRP-C24H and TRP-C26H are paired, they can support 16 channels remote control does not require any
drivers and software support.
The TRP-C24H is also offers the maximum connection 16 host client to link the network server that is easy to
operate in Modscan32 ,Modbus Poll,CAS Modbus Scanner and SCADA ...application uses TCP mode and

3.Install TRP-C24H Hardware
STEP1: Connect power source with TRP-C24H, the PWR LED will blinking.
STEP2: Connect TRP-C24H with netwotk by RJ45 cable.
If the cable is properly connected the “LINK” LED will light up.
*The TRP-C24H Support Auto-MDIX, A straight-through or crossover RJ45 cable can be used to make a connection
directly to the HUB/Router/PC LAN port.
STEP3: Connect TRP-C24H screw terminal wiring, such as 2-5 picture description.
4. How to configure TRP-C24H
*Please note that the computer's IP segment adjusted with TRP-C24H same section, modify the parameter values in
order to effectively store!
For example:
Computer IP is 192.168.1.xx
TRP-C24H 192.168.1.1
There are 2 ways can change the module parameter values.
A.DSM Software
B. WEB Server
6
4-1. Using DSM Utility
The DSM utility software performs several functions:
A: Searching for TRP-C24H connected to the network.
B: Displaying and changing the configuration.
C: Upgrading the TRP-C24H firmware, Refer the Firmware upgrade help file.
D: Saving and Loading Configuration from external log File or EEPROM.
4-2. Searching TRP-C24H
Once TRP-C24H is connected to the network the DSM software will search it and display it in a window by name, IP
address, Mac….Information.

9

Gateway
Input the gateway IP address that can be allows users to access the serial server from internet.

DNS
Short for Domain Name System, an Internet service that translates domain names into IP addresses. Because
domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses.
Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP
address.


Transmit Timer: This feature is only available to Serial Server TRP-C37 and TRP-C37M.
Maximum Connection: 1~16
The function allows the user to configure the TRP-C24H in Server mode, adjust 1~16 TCP client host connections.


When TRP-C24H in Server or Client mode, the TRP-C24H without data over the 1~7 Min setting value,
The TRP-C24H will be disconnecting TCP port.

New Password: 1234
It only accepts value from1000~9999 integer, if input the wrong password over 5 times, the WEB-Page will lock until
the TRP-C24H re-boot.


Firmware Version: ABC
Slave ID:1~255.
ID performs MODBUS RTU / ASCII and TRP-ASCII will use to address.

LED Display Panel Setting :ON/OFF
The setting will turn on all panels LED or Turn off panel LED.

Polling Setting: High/Low.


System Mode
Power ON Mode: Digital output state when the TRP-C24H Power On.
Save ON Mode: The digital output state when the TRP-C24H is working, Once this mode is set, the digital output
state cannot be rewritten.
Pair Mode: It can be used as a remote manual remote control, when the TRP-C24H 16 DO and TRP-C26H 16 CH
DI, TRP-C28H 4 D I/O with TRP-C28H 4 D I / O. Without any driver.
Trycom Checksum setting: Disable/Enable.

4-4.Using the WEB Server mode
The Web Server can be used to configure the TRP-C24H from any web browser software (such as I.E).
In Internet Explorer type the IP Address of the TRP-C24H into the address field and press the Enter key. The
following window will appear:
Example:
If TRP-C24H IP is 192.168.1.1 Please Input the 192.168.1.1 then enters at web address, the web-page will
appear.
11
4-5 TRPCOM Test Utility
The TRPCOM test utility may help to use the debugging program development phase, the user can find this
software in our CD internal directory copied to the hard disk, and then directly execute TRPCOM.exe.
TRPCOM utility can automatically detect the model, it will list the corresponding function key,
It helps developers to understand and control the digital state.

5. TRP-ASCII Communication Protocol
TRP-C24H supports three modes of communication Protocol TRP-ASCII, Modbus RTU, Modbus ASCII.
TRP-ASCII Command Protocol Description
Command Format :”Leading Code”+”ID Address”+”Command”+”CHK”+(cr) .
at :”Leading Code”+”ID Address”+”Data”+”CHK”+(cr) .
How to calculate the checksum
1. Calculate all characters of the command string to get the ASCII sum, except the character return.
2. Mask the sum of string with 0FFH.
Example:
Send the command is “$06M”.
Sum of string is “$”+”0”+”6”+”M”=“24H”+”30H”+” 4D“=“A1H”……The checksum and [CHK]=“A1”.
Response string with checksum is :” A1“.
TRP-ASCII: ease of use TRP-ASCII integration to develop their own software, such as VB, VC .

6. Modbus RTU/ASCII Communication Protocol
* For more modbus RTU / ASCII protocol specification, please download from http://www.modbus.org website.
Obtain more modbus TCP instruction test, we recommend user can be downloaded from the following Web site
Modbus Poll Test utility http://www.modbustools.com/
Modbusscan Test utility http://www.win-tech.com/html/modbus1.htm.
User can use the virtual-com program with TRPCOM.exe for Modbus RTU test; these programs can be found in our
directory of the CD!
Install the Virtual-COM
Step 1. Insert the TRP-Serial CD and find the TRP-C24H folder.
Step 2.Click “Vcomm.exe” icon then install Virtual-COM utility.
*The Virtual COM utility support multi-language, please select which language do you need.
Step3. Click “OK” button and select “VSP run as Client support Server Device”.
Step4. Select “Create virtual serial by device scanner”, then press “OK”
23
Step5. Run VCOMM.exe then click right button select “New Virtual COM”
Step6. Select “Select Serial Port” and input TRP-C24H IP and port then press “OK”.
Step7. If Virtual-Com setting success, the display will appear bellow.
Step8.Run TRPCOM utility then select virtual-com port make a TRP-C24H command.
*If in VCOMM‘s configuration select “Boot with windows”, the virtual-com will Auto-connection when windows start.
24
* TRP-C24H in use the Virtual com mode, the default data format is 9600, N, 8,1, this mode is not allowed to
change.
